Appeal No. 1999-2028
Application No. 08/769,036
Appellants' invention relates to a telephone handset that
includes circuitry that transceives both analog cellular
signals and also cellular digital packet data (CDPD) signals.
Claim 67 is illustrative of the claimed invention, and it
reads as follows:
67. A telephone handset that communicates with analog
cellular signals and with cellular digital packet data (CDPD)
signals over frequency channels, comprising:
analog cellular signal circuitry that transceives analog
cellular signals;
CDPD signal circuitry that transceives CDPD signals; and
a control processor, coupled to the discriminating
circuit, that controls the analog cellular signal circuitry
and the CDPD signal circuitry such that the CDPD signals are
transceived over the same frequency channels as the analog
cellular signals.
The prior art reference of record relied upon by the
examiner in rejecting the appealed claims is:
Braitberg et al. (Braitberg) 5,479,479 Dec.
26, 1995
Claims 67 through 69, 71, 73 through 84, 87 through 93,
and 95 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Braitberg.
Reference is made to the Examiner's Answer (Paper No. 51,
mailed April 14, 1998) for the examiner's complete reasoning
